After driving both I personally like the turbo 4 more.

The turbo makes it feel faster to me. Although there is a good deal of turbo lag and the V6 accelerates quicker to 60, once the turbo spools up you are glued to your seat.

Which would you guys prefer?

 

This will start another internal C Coupe forum war. Different taste + different people needs. If you search the forums, this topic has been discussed and beat to death.
================================================== =

To fix your lag I recommend driving hard in S mode. Let the ECU learn your driving habits and you will have minimal turbo lag. I have BMS tune + custom exhaust and Intake. Lag is non-existence in my car in "S" mode.

 

I've had a few turbocharged engines, including a 135i, and honestly prefer the characteristics of N/A engines better. To each his own.

 

Agree, people who got I4/C250 please stop these posts, your car is OK and please move on and get over it ...

 

I didn't mention C250 or C350 for a reason.. I just mean turbo 4 and V6 in Mercedes in general, even BMW.. I've driven a bunch of both

 

Agreed!! Wow we agreed on something lol

 

In that case, I think MB is headed in the right direction. They are still behind like BMW and Audi with the I4 but they are getting there with the CLA45 and A45. I would love to have CLA as a daily commuter. 350+ hp out of a turbo i4 is ridiculous. BMW F30 328 is also really good. Little turbo lag in that car and it hauls ***. If MB comes out with a bi-turbo v6 option for the c class then that will be even better. I4 turbo < v6 Turbo

 

Didn't I said get over it? I was hopping I don't need to tell you again that V6 is ...

 

Actually a 6.2l V8 isn't a bad way to go in this car either.

 

Agree with some of the comments above regarding where this thread can lead to, so hopefully it'll stay on topic

It is one of those things that's definitely a case of each to their own.

For mine having owned and still the owner of multiple car types with both forced induction and N/A of all types my preference is definitely towards forced induction

 

Not a fan of this 4cyl turbo lag I sold my 2010 Audi A4 because of it. The C350 and c250 are very different cars besides the HP the brakes in the c250 suck I dont know why MB put small disk in that model. The c350 has much larger disks and the stopping power is truly incredible.

 

It depends on the market.

Here in Australia, the C250's have or can have everything the same as the C350 except of course the engines.

So a C250 petrol with the larger brakes will stop better than a C350 because it's lighter, the C250 diesel is heavier though, also there's no such thing as lag in the twin turbo C250 diesel, 370lb/ft torque from just off idle

 

Your absolutely it does depend on the market. I should have said US spec. But can you tell me what is the HP rating for the C250 diesel?

 

I would like to know the answer to that as well. Wow, if we had a diesel option, I would have been all over that. That is essentially 100tq+ than the c350 v6 model. Can you say tune? Damn you can essentially get the Euro models to probably 400+ tq with a tune.

AV1 - Do you have the turbo diesel model? No wonder you have been defending the c250 so much. If I had the diesel with that much torque, there is no way I would even look at the v6. Sound or not.

 

C250-CDI = 150kw (201bhp) 500nm (369lb/ft) stock.

Same hp as the C250 petrol but with over 60% more torque and more importantly average fuel efficiency double that of the C250 petrol

 

Yep, it's in my sig for all to see - "drives a C250-CDI" check out the other thread where some of us are now running a tune, also it's actually a twin turbo

And yes as for the choice of variant I'm certain that with the option of the diesel many more would've picked it too, here in Aust. it's the best selling C Coupe variant simply because it offers the best of all Worlds

 

It's the ultimate pic for performance if that's what one wants, but unfortunately fuel consumption on that variant is horrifying in a market where fuel prices are sky high, running/service costs and consumables costs are multiple times that of any other variant and in Aust. you pay a hefty premium on an already mega expensive car market to get one, ie. the better part of $200k

 

yee right, that is why diesel never been used by any sports racing cars and never will tons of torque while low rpm is good ... but for train or bulldozer ...

 

It's used and a constant winner in Euro DTM races

It's been slow to spread, but more importantly is its use as common daily street driven vehicles not racing and there is where it excels, plenty of performance and outstanding efficiency and running costs.

The trend looks like never taking off in the U.S however it's gaining momentum in Countries like Australia and it's old news for the Europeans.

The technology is ever improving, before this latest generation of diesels I too would never have opted for one, but now they're hitting all the right buttons.

FYI or your own curiosity check out the new upcoming BMW tri turbo 3.0ltr IL6 diesel engine which will feature in new BMW models, it outputs 280kw (375bhp) and 730nm (550lb/ft) why would you opt for the equivalent in petrol especially considering an average return of 6.5ltrs/100km efficiency, will be interesting to see how MB and Audi respond with their next gen diesels

For people like yourself, I only wish you could get your hands on a C350-CDI and then come back and tell me if you still prefer your C350 petrol, if MB had ever made a C350-CDI coupe variant it would render the C350 petrol redundant

 

I am not against of diesels, but they are not superior to gasoline engines anyhow. Besides noisier and dustier by nature. Sports? Any place where you need high RPM diesel is out, and most of them are. I can't see diesels on F1 cars or super-bikes for example

 

Believe me I'm not a diesel fan boy either, only trying to point out the facts about modern diesels in passenger vehicles, especially those in our MB's which are brilliant

This C Coupe MB of mine is my first diesel ever after nearly 30 years of petrol cars, I still own many other cars all of which are petrol, from 2.0ltr turbo to N/A V8 LS1 and even an Opel 2.5ltr N/A V6, none of those can combine the all round package of power, performance and efficiency of the 'little' MB twin turbo diesel in my C250-CDI.

This newer gen of diesels are not as noisy as the previous ones, granted noisier than petrols yes but in terms of output noise the V6 and V8 diesels emit an exhaust note almost exactly the same as their petrol counterparts which is not such a bad thing and in the case of MB's passenger cars they run completely clean, I've never seen a puff of soot or black smoke come out of mine or any other newer diesel MB passenger car, the DPF does its job very well, older SUV diesels threw out lots of soot by comparison

Agree with you about the use on certain performance orientated applications, however as already noted that is slowly changing, Audi have a planned R8 diesel variant that puts the petrols even the Lambo sourced V10 to shame, already mentioned the new BMW diesel tri-turbo IL6 which will out perform the current same displacement petrol turbo N54 and N55 3.0ltr turbo petrol IL6's and that trend will only continue in future.

Will be interesting to see what MB comes up with, so far they've developed a hybrid diesel electric combo for future C and E class models which should result in even more explosive torque and economy outputs, but hopefully they'll release higher power output diesels in a similar direction BMW is going
